Howard Marks, Nima Shayegh & William Green on Essential Truths, Humility, and Stoic Resilience

RWH066 | Richer, Wiser, Happier | 21 February 2026 | Episode page

Host: William Green Featured voices: Howard Marks, Nima Shayegh

A compilation episode. Green curates clips from his two most recent interviews — RWH063 with Howard Marks and RWH064 with Nima Shayegh — and comments on the lessons he wants to retain. Closes with a personal reflection on Stoicism, prompted by Bill Miller and Epictetus, during a period of personal challenge.

Key ideas

  • Humility as edge. Both Marks and Shayegh — and Shayegh’s mentor Lou Simpson — treat intellectual humility not as a virtue but as a perceptual instrument: ego distorts judgment; its removal sharpens it. Marks: “I belong to the I don’t know school of thought.” Simpson would say “Maybe you’re right, I should think about that more” rather than defending a position.
  • Uncertainty demands positioning, not prediction. Marks on AI: it will change the world, but “change the world and investors making money are not the same thing.” His advice — understand your risk posture, avoid binary bets you cannot afford to lose, and align with intrinsic value rather than narrative. Buffett’s corollary: productivity gains need not accrue to the provider of the technology.
  • The even keel. Marks’s prescription for long-term investing: invest early, invest a lot, don’t tamper. Markets work because economies grow and companies improve profitability; the investor’s job is to stay on that trajectory, not to optimise entry and exit. “Don’t just do something, sit there.”
  • Roots before branches. Shayegh’s summary of Roots and Branches: the investment industry fixates on quantifiable surface data (branches); competitive advantage lies in perceiving the qualitative causal forces (roots) upstream of financials — management motivation, culture, product excellence. Lou Simpson: “All investing is figuring out the future economics of a business.”
  • Stoic grounding. Green on Epictetus and Stockdale: what one controls is the inner response, not external circumstance. Epictetus’s actor metaphor — “act well the given part” — applied to illness, difficulty, and ordinary human failure. Bill Miller, drawing on Epictetus through the financial crisis: “Focus only on what you can control.”

Structure

  1. Howard Marks clip (AI and euphoria) — AI vs dot-com bubble; trees grow to the sky; winners are not guaranteed to remain winners; lottery-ticket mentality.
  2. Howard Marks clip (emotional even keel) — buy-and-hold temperament; even keel as competitive advantage; future as probability distribution, not single outcome.
  3. William Green commentary — risk posture calibration; Marks’s distillation of practical wisdom; the prosaic discipline of long-term investing.
  4. Nima Shayegh clip (branches and roots) — UCLA maths background; the industry-wide over-quantification problem; cheshm del (eye of the heart); “blown awayness” as quality signal; Tesla FSD as example.
  5. Nima Shayegh clip (Lou Simpson) — first meeting in Chicago; Simpson’s ego-less manner; few holdings, high patience; going to the MoMA during a down market; “do a lot of thinking and not a lot of acting.”
  6. William Green reflection (Stoicism) — Epictetus, Stockdale, Bill Miller; “each individual brings about his own good and his own evil”; the actor metaphor; self-compassion.
